HarmonyOS 鸿蒙Next errorManager error事件的onException回调触发时机

onUnhandledException和onException监听的是同一种异常。监听到的异常场景都是一样的，只是onUnhandledException回调的是字符串，onException回调的是错误对象。可以看api: https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/js-apis-inner-application-errorobserver-V5

示例demo:

在EntryAbility中，设置异常监听

let observer: errorManager.ErrorObserver = {
  onUnhandledException(errorMsg) {
    console.error('onUnhandledException, errorMsg: ', errorMsg);
  },
  onException(errorObj) {
    console.log('onException, name: ', errorObj.name);
    console.log('onException, message: ', errorObj.message);
    if (typeof (errorObj.stack) === 'string') {
      console.log('onException, stack: ', errorObj.stack);
    }
  }
};

export default class EntryAbility extends UIAbility {
  onCreate(want: Want, launchParam: AbilityConstant.LaunchParam): void {
    hilog.info(0x0000, 'testTag', '%{public}s', 'Ability onCreate');
    try {
      let reid = errorManager.on('error', observer);
    } catch (error) {
      console.error(`registerErrorObserver failed, error.code: ${error.code}, error.message: ${error.message}`);
    }
  }
}

在index.ets中创造异常：

aboutToAppear(): void {
  setTimeout(() => {
    let tempList = ['0', '1']
    tempList[5].toString()
  }, 100)
}
